公司依靠先进的质量管理体系，雄厚的技术开发力量—在不断地以顾客需求为关注焦点的宗旨下，致力于我国真空阀门的发展，创造性地不断推出性能可靠，外形美观的产品，有手，气、电动的蝶阀、隔膜阀、挡板阀、电磁压差阀、电磁截止阀、球阀、插板阀等10多个系列真空阀门，以及各种规格和型号的高中低压阀门和水力控制阀门。

This less restrictive flow path design improves flow while maintaining the same excellent throttling characteristics as a globe valve.

这种结构对流道的阻力较小，从而在保持截止阀具有相同的节流性能的基础上改善了截止阀的介质流动性。

Common type oil mist device in a state of fuel inlet, when plug 10 as long as the screw pine oil, the oil cup on the cavity c they pass the atmosphere, at the same time, enter the incoming compressed air will be cut-off valve spool 2 pressure in the cut-off valve seat 4 on, cut off the passage of compressed air into the c-cavity.

普通型油雾器能在进气状态下加油，这时只要拧松油塞10后，油杯上腔c便通大气，同时，输入进来的压缩空气将截止阀阀芯2压在截止阀座4上，切断压缩空气进入c腔的通道。

A cut-off function, the installation of the balance valve will not have to install the valve.

有截止功能，安装了平衡阀就不必再安装截止阀。

According to the clear water experiment, aeration performance of the new equipment is good with high total oxygen transfer coefficient and oxygen utilization ratio.

曝气设备的动力效率在叶轮转速为120rpm～150rpm时取得最大值，此时氧利用率和充氧能力也具有较高值。

The environmental stability of that world - including its crushing pressures and icy darkness - means that some of its most famous inhabitants have survived for eons as evolutionary throwbacks, their bodies undergoing little change.

稳定的海底环境─包括能把人压扁的压力和冰冷的黑暗─意谓海底某些最知名的栖居生物已以演化返祖的样态活了万世，形体几无变化。
